Overview

The main purpose of the Sensor is high precision measurement of speed and traveling distance of the vehicle relative to ground (automotive and railroad application) and speed and length of objects moved relative to the sensor (industrial application).

Broad range of nominal working distances – from 10 cm to 150 cm and it can vary up to 2,5 times during measurements.

Big lens aperture – geometric aperture ratio up to 1:4. As a sequence, 10 Wt of halogen lamp or even IR diode of 2 Wt electrical power is enough for Electromagnetic compatibility object illumination in most cases

Low weight and power consumption of controller module (1,5 Wt) due to last generation of ARM microcontrollers used.

Use supply voltage and interfaces indicated in the sensor specifications.

In connection/disconnection of cables, the sensor power must be switched off.

The sensors have been developed for use in industry and meet the requirements

Currently ISD-3 family included 2 models with different versions with working range from 10 cm up to 100 cm and more. Custom-ordered configurations are possible with parameters different from those shown below.

Coming soon are 2-Dimentional sensors to measure, for instance, longitudinal speed of rotating tubes in tube-rolling mill, or transversal displacement of moving objects.

Although a special version of sensor for road application in automotive testing industry will be available soon.
